Radiomics has been proven effective for the characterisation of primary prostate cancer (PCa).1,2 However, the limited interpretability of the proposed models represents one of the major limitations in this field.

Renal cell carcinoma (RCC) is the most common malignant kidney tumour, with clear cell RCC (ccRCC) accounting for 70–80% of all cases. Approximately 15–20% of patients have primary metastatic RCC at diagnosis, and 15–20% of those who receive curative treatment for localised tumours will experience recurrence within 5 years of follow-up.

Urothelial carcinoma in situ (CIS) of the bladder is an intra-epithelial, high grade, malignant neoplasm characterised by flat (non-papillary) growth, with high probability of disease progression.

To retrospectively evaluate the safety and efficacy of CT-guided percutaneous microwave ablation (MWA) of small-sized (≤2 cm) hepatocellular carcinoma (HCC) regarding therapy response and survival rates. The goal is to compare data from minimal invasive treatments like MWA and radiofrequency ablation in comparison to surgical resection or data from liver transplantation.

The high incidence of bone metastases, particularly vertebral metastases, in patients with cancer and the limitations of conventional treatments are the main challenge for the interventional oncology specialty.

Vacuum-assisted biopsy (VAB) is performed when a breast lesion appears suspicious at imaging examinations. Although several different modalities can guide the biopsy, some lesions can only be visualised by imaging modalities that can depict tumour neo-angiogenesis. For this type of lesion, MRI is the most sensitive modality when lesions are occult at second-look ultrasound or mammography.

Dynamic myocardial CT perfusion (CTP) is a relatively novel technique that can depict myocardial ischaemia. However, the radiation dose required for dynamic CTP remains relatively high. Therefore, the authors investigated the feasibility of dose reduction in dynamic myocardial CTP by comparing the diagnostic performance resulting from acquiring images during all heartbeats to that involving the periodic skipping of imaging during a certain proportion of heartbeats.
